External Mastic in Eversley
Problem with your movement joints in Eversley? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Weathered mastic that no longer stretches
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
What happens if it’s left?
Resealing a run of joints in one go is usually better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Around Eversley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Why book with us

How we handle external mastic in Eversley
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. Common call-outs are for plants rooting in failed movement joints and rain getting behind render or cladding at a joint, on render & cladding joints, copings & trims and concrete & block.
External sealant needs dry, clean surfaces, so work around Eversley is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.

What external mastic looks like in Eversley
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stratfield Saye House (about 4.7 miles west) are a reminder that the area around Eversley has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Crowthorne station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Charles Kingsley's Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Eversley
I let a flat near Crowthorne station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover Eversley for external mastic?
Yes. Our work covers London and the South East, and Eversley is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
What does external mastic cost?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How we quote for external mastic
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- How much there is to do
- Whether old sealant or filler has to be cut out
- Whether the work is at height
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.
Asking for a quote
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
- Where the property is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
How it works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Eversley, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we are working on
- Plan for the work area to be out of bounds to pets and children

Advice
Aftercare tips
So the new joints stay in good condition:
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
- Check external joints each spring
- Leave the joints unpainted unless we’ve said otherwise
Don’t paint over the new sealant unless we have said the product is paintable. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
Do you need external mastic in Eversley?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
People generally contact us after spotting one of these:
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- How the colour is chosen
- Is the old sealant removed completely?
- How much experience the applicator has
- Whether VAT is included
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
